Incoherent alluvium
Did you know?
WebWhen a channel is flowing through a material that can be scoured easily then such soil is known as incoherent alluvium. 2. Initial Regime: A channel is in the initial regime when the bed slope gets affected due to silting and scouring. The regime theory is not valid for the initial regime. 3. Final Regime: Webin incoherent alluvium is of great value to irrigation engineers. In 1930, he proposed the equation P = 2-668Q1'2 connecting the * Regime Flow in Incoherent Alluvium. By Gerald …

Lacey’s Regime TheoryLacey’s Regime Theory Gerald Lacey -- 1930 Lacey followed Lindley’s hypothesis: “dimensions and slope of a channel to carry a given discharge and silt load in easily erodable soil are uniquily determined by nature”.
